Different with our eyes that work well in day light, the cat’s eyes can function well in very low light situation. In the dark, cat’s eyes only need about one-sixth of the light required for human sight as the cat’s elliptical pupil are able to open as wide as possible to allow the light entering the eyes.
Tapetum lucidum that located at the back of the cat’s eyes –behind the retina- performs like a mirror that will reflect back the light onto the light sensor cells in the retina. That’s why when those eyes are caught in a ray of light at night, we see two amazing glowing eyes!
